On a 90cm offset motorized dish what would be the optimum length for the cable from the motor to the lnb? I don't want to be too short, of course, but on the other hand I don't want an excessive amount to have to loop and tie up.
I usually make a loop and loosely nylon tie as shown in this photo. If I need to reroute, put on a new connector or if the dish somehow gets loose and spins in a bad storm, the spare coax length comes in handy!
